Summary:
As promised, this week we will be going over how to add client-side JavaScript to a custom validator control. But last week I was asked a very interesting question. What validator control should I use to validate that a CheckBox was checked within a CheckBoxList? The anwser was simple, NONE. None of the validator controls in the .NET valiator control suite does this type of validation. So, in this article not only are we going to discuss how to add JavaScript validation control for client-side validation, but how to create a CheckBoxListRequiredFieldValidator control. |
